Description

Technical Field

[0001] The utility model relates to the technical field of material drying, in particular to a material drying system. Background Art

[0002] Three-in-one equipment refers to the process of filtering, washing and drying being carried out in the same equipment. It is widely used in the pharmaceutical, pesticide, chemical and other industries. The traditional three-in-one drying method is to heat up the three-in-one jacket and use a vacuum pump to bring hot air into the three-in-one, and rely on the flow of air to take away the solvent to achieve the drying effect.

[0003] Existing drying equipment is only used for drying raw materials. To achieve solid-liquid separation and solid washing, drying and unloading after separation, other equipment is needed to assist and cooperate. At the same time, in the drying process, the moisture (generally referring to water or other volatile liquid components) in the material is vaporized and escaped only by heating, and the drying efficiency is low, which affects the subsequent steps.

[0004] The existing patent (Announcement No.: CN210512345U) is a three-in-one drying equipment. This utility model adopts a reasonable structural design. First, the centrifugal filter cartridge inside the shell is threadedly connected to the support column through the bolt passing through the fixing ear, and then the centrifugal filter cartridge is fixed between the support frame and the support column, so that the centrifugal filter cartridge can be removed to complete the unloading of the solid raw material after the subsequent operation is completed; then the servo motor drives the rotating shaft and the support frame to rotate at a high speed, drives the raw material in the centrifugal filter cartridge to rotate centrifugally to complete the preliminary separation of solid and liquid, and then opens the shell cover to install the support shaft and the stirring shaft, and the water pump sprays water from the cleaning port, and the solid raw material is washed by the centrifugal filter cartridge rotating at a low speed under the action of the stirring shaft. After washing, the high-speed rotation removes moisture, and then steam is added through the steam inlet. The heat exchange tube releases heat in the shell to increase the temperature and then is discharged from the condensation outlet. While drying the solid raw material, the centrifugal filter cartridge rotating at a low speed stirs the solid raw material under the action of the stirring shaft, which accelerates the drying efficiency of the solid raw material. The overall operation quickly completes the solid-liquid separation and the washing, drying and unloading of the separated solid.

[0005] In view of the above problems, the existing patents have provided solutions. However, because steam is added through a steam inlet, the air flow is relatively small, which not only slows the drying speed, but also poses certain safety hazards when hot air is introduced. The use of a three-in-one jacket to increase the temperature can easily cause uneven heating, causing the material to melt into balls and reduce product quality. In particular, for solid materials with a relatively low melting point, the drying speed is very slow and requires more than ten hours.

[0006] Therefore, a material drying system is proposed. Utility Model Content
